Commercial tenant improvements

Tenant improvement electrical contractor in Seattle, Tacoma and Bellevue

Tapps Electric builds the electrical systems for commercial tenant improvements across Western Washington. We work for general contractors on office, retail, lab, fitness and public agency spaces, from a single-suite refresh to multi-floor build-outs.

A tenant improvement lives or dies on schedule. We read the full drawing set before we bid, raise conflicts early, and staff the job with union electricians who are used to working around other trades in a tight ceiling.

Tenant improvement electrical scope

  • Make-safe and selective electrical demolition
  • Panelboards, transformers and tenant distribution
  • Branch power, floor boxes and furniture feeds
  • LED lighting and lighting controls that meet the Washington State Energy Code
  • Power for HVAC, kitchens, labs and tenant equipment

Working in occupied buildings

Most tenant improvements happen in buildings that stay open. We plan shutdowns with building engineering, work after hours when the lease or the neighbors require it, and keep common areas clean. Our crews have built out retail on Stone Way, state offices in Kirkland and lobby space in South Lake Union.

Pricing a TI the way general contractors need it

Our bids are built to be leveled: clear inclusions, clear exclusions and no padding. If the drawings leave something open we say so in writing instead of burying it. When scope changes during construction, we document it with an RFI and a detailed change request so the owner knows exactly what they are paying for.

Common jobs we get called for

Tenant improvements: common questions

What size tenant improvements does Tapps Electric take on?

Our typical electrical package runs from about $200,000 to $4 million, and we also handle smaller suites for repeat clients and building owners.

Can you work nights or weekends in an occupied building?

Yes. Off-hours work, planned shutdowns and noise restrictions are a normal part of tenant improvement work and we price and schedule for them up front.

Do you handle design-build tenant improvements?

Yes. When there are no engineered electrical drawings we can provide design-build pricing and permit drawings with our engineering partners.

Need a price on tenant improvements?

Send plans, specs and the due date. We read every sheet and tell you quickly whether we are in.
